From d635fbe27ebee0f4b845abe5e9620c9400785a5c Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Tue, 16 May 2017 14:00:03 -0700 Subject: tcp: use tcp_jiffies32 to feed tp->lsndtime Use tcp_jiffies32 instead of tcp_time_stamp to feed tp->lsndtime. tcp_time_stamp will soon be a litle bit more expensive than simply reading 'jiffies'.
